摘要:
A method is provided for making a high repellency material. In one embodiment the method includes the steps of providing a polymeric material having an external surface including particle-like nanotopography, etching the external surface with a high energy treatment; and depositing a fluorochemical onto the etched external surface by a plasma fluorination process.

A method is provided for making a high repellency material. In one embodiment the method includes the steps of providing a polymeric material having an external surface including particle-like micron-scale topography, etching the external surface with a high energy treatment; and depositing a fluorochemical onto the etched external surface by a plasma fluorination process. The external surface may define a plurality of micro-tears proximate the micron-scale topography.

A face mask for reducing the amount of microbes to which a wearer is exposed is provided. The face mask includes a body portion that has an outer layer that has been treated with a germicidal agent in an effective amount. The layer may be a nonwoven fabric like a spunbond, meltblown or coform layer and may be a laminate of such layers. The face mask having such a germicidal treatment can result in a reduction in microbial activity as compared to another face mask, identical but for the germicidal agent.
摘要:
As described herein, an abrasion resistant nonwoven fabric includes fibers having an external surface covered with a treatment selected from the group consisting of organosilicone compounds applied by plasma treatment in inert gas without the presence of oxygen and acrylic monomers having a Tg greater than or equal to 20 degrees C. applied onto the nonwoven fabric and subsequently surface grafted and crosslinked via exposure to plasma glow discharge or e-beam without the presence of oxygen. The treated fabrics demonstrate improved abrasion resistance over untreated fabrics.

A laminate is generally provided having alcohol repellency properties. In one particular embodiment, the laminate includes a meltblown web bonded to a spunbond web (e.g., a SM laminate, a SMS laminate, a SMMS laminate, etc.). A fluorinated polymeric coating is attached to the surface of the spunbond web (e.g., grafted). The fluorinated polymeric coating comprises a perfluoroalkyl(alkyl) (meth)acrylate monomer polymerized on the surface of the spunbond web via exposure to a low frequency energy source. The perfluoroalkyl(alkyl) (meth)acrylate monomer has a perfluoroalkyl side groups comprising —(CF2)z—F, where z is an integer from 1 to 6. The laminate has an alcohol repellency of greater than 80%.

摘要:
Methods of manufacturing a nonwoven web having alcohol repellency properties are provided. A plurality of perfluoroalkyl(alkyl)(meth)acrylic monomers can first be deposited on a surface of the nonwoven web, and subsequently exposed to a RF plasma to polymerize the monomers on the surface of the nonwoven web to form a fluorinated polymeric coating. The perfluoroalkyl(alkyl)(meth)acrylic monomers include perfluoroalkyl(alkyl)(meth)acrylate esters having a perfluorinated carbon end group of 1 to 6 carbon atomsNonwoven webs are also generally provided that have an alcohol repellency of greater than 80%.
摘要:
The present disclosure is generally directed to hydrogel-fibrous web composites that can be used in a variety of applications. For instance, the hydrogel-fibrous web composite can be used in the same applications as the base fibrous web, without the addition of the hydrogel, when it is desired to increase the moisture or water absorbency of the web. The hydrogel polymer is integral to the fibers of the web. Thus, the hydrogel allows the web to absorb water or moisture (including water vapor) to a much greater extend than the web alone. The present disclosure is also generally directed to methods of integrating a hydrogel polymer into a fibrous web.
